GNOME on Wayland current status

[Rutger Helling]

Hello Guix,

As discussed in patch #29758 I've tried GNOME on Wayland on the 
different display managers.

SDDM: Should work, just pick the "GNOME (on Wayland)" session.
SLiM: Doesn't seem to work. I'm not sure if SLiM has support for Wayland 
sessions at all.
I couldn't get GDM to start, so I don't know if that works or not.

Note that you can use the following command to manually start GNOME on 
Wayland:
XDG_SESSION_TYPE=wayland dbus-run-session gnome-session

This seems to require that you've started GNOME via a display manager 
first though.
